You can choose where to put the food according to your favorite taste. Some people like it to be deep roasted, while others like it to be just tender.
If you need to grill food that is colored quickly, for example: chicken wings, steak and other meat, it is suggested that you put it in the middle or upper layer.
If you need to grill food that is colored slowly, for example: macarons, cake, bread and other pastries, it is suggested that you put it in the lower layer.
For other dishes, it is suggested that normally they can be put in the middle layer.
